VAPOR OIL-BURNER.

Application filed October 18, 1919. Serial N0. 331,6 49.

To all whom z'tmay concern:

Be it known that I, BENHOWER, a citizen of the United States, and aresident of Anderson, county of Madison, and State of Indiana, haveinvented a certain new and useful Vapor Oil-Burner; hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawlngs, in which like numerals refer toY like parts.

This invention relates to vapor oil burn is an improvement on theinventlon shown in Patent No. 827,764, dated August 7, 1906.

The ob ect of this invention is to provide, by the rearrangement of theparts and the addition. of air vents, for the complete come bustion ofthe fuel in the structure described in the before mentioned patent.

The full nature of this invention Will be understood from theaccompanying drawings and the following description and claims.

In the drawings Figure 1 is a central cross section of the improved oilburner ken on the line 1-1 of Fig. 2. Fig. 2 is a plan view of theburner with the reflectmg means omitted.

In the drawings indicates a pipe lead ing from any suitable supply ofoil, such as kerosene or the like. ll-is a pipe leading therefromhorizontally and then vertically into the burner. A valve 12 is providedfor controlling the supply of fuel to the burner. The verticallyprojecting portion of the pipe 11 is threaded at its upper end toreceive the dome 13, the same having an upwardly extending rim 14concentric therewith and a discharge outlet-15in the center thereof. Thedome, While hollow, is rather thick and solid, especially in the upperortion, so that it will hold considerable heat, and about its base thereis a. series of Vertical air holes 9.

Under the dome 13 there is a drippingpan 16, preferably scalloped at 17so that air may pass freely from the front of the stove in which theburner is located. In

the center of the drippin -panthere is acentral hole 18 through w ichthe pipe 11 extends. Four stands or supports 19 are s need an equaldistance from each other in tiie dripping pan 16, and notched orshouldered to receive and support what may be termed an oil ring or oilpan 20, which is Specification of Letters Patent.

Air passages 24.- are provided between the lnner rim 22 and the pipegulde 23 by the guide supporting portions 25. The oil ring is alsoprovided with a plurality in the form of tu es.

' he outer and upper edge of the ring 20 1S suitably rooved to receiveand support a casing 2 lower portion and an enlarged tion 28 providing acombustion 29. A perforated heating plate pair of large outlet open-These latter openngs are coveredby deflectors 33 that are supported onlegs 34, the same being notched at then lower ends'to rest looselywithin the openings 32 and on the top of the plate 30.

he casing 27 is provided with a' pair of openings 35 registering withthe openings 32, to provide for the introduction of additlonal air inthe combustion chamber 29. The dripping pan 16 has two openings 36'provided in its base, and threaded in said openings are the tubes 37extending upwardly into communication with the combustion chamber 29through the openings 35.

From this description it is observed that the oil burner is providedwith a plurality of air passages for vaporization and partial combustionof the fuel, and in addition there is provided the auxiliary air tubes37 which supply oxygen to the flame in the mixing and combustion chamber29 at a point where the flames are. coolest. Thisv provides for thecomplete combustion of the fuel before the flames pass out through theopenings 32.

Herein it will be observed that the centralopening-18 not only su pliesair to the combustion chamber throug the passages 9 and 24, but alsosupplies air to the tubes 26 as shown by the arrows in Fig. 1. With thisconstruction a better draft through the tubes either the openings 32, 3I or 18. The burl;-

of alrbopenings 26 herein shown the same having a flared let therein theoilas it passes 15 wherethan half 1. An oil burner comprising means forsupplying oil thereto, a dome having an outand a portion over which theoil may flow, anoil pan dome and having a plurality of upwardlyextending tubes for the admission of air, a casing concentric with andsurrounding said dome and enlarged at its upper end to form a combustionchamber and having an airopening therein, a heating plate surmountinsaid casing and closing the same,

pan supporting said oil pan, said drip pan having allilif-OPGliiIlgtherein, and means connecting said air openings in the drip pan and thecasing.

2. An oil burner comprising means .for

11 andthe dome 13.

before it is entirely concentric with the h said plate havlng aflame'opening therein, a drlp,

supplying oil thereto, a dome having a discharge outlet and-providing 'avaporizing surface for" the fuel, an oil-pan concentric with the domeand having a plurality of openings therein for the admisslon of air, acasing surrounding said dome and having an enlarged portion providing acombustion chamber, a plate having a flame opening and closing saidchamber, said casing having an air opening therein registering with saidflame opening in said plate, and tubular means secured in said casingair-opening and extending downwardly therefrom.

3. An oil burner comprising means for supplying oil thereto, a domehaving a discharge outlet and a portionover which the oil may flow andbe vaporized, a casing surrounding said dome and providing a combustionand mixing chamber therein, an oil pan concentric with said dome andbeneath the same, said pan having a plurality of openings therein forsupplying air to the mixing and combustion chamber, and a plurality oftubes extending downwardly from said casing for providing an additionalsupply of air to the combustion chamber for the complete combustionofthe fuel.

In witness whereof, I have hereunto af-.

fixed my signature.
